Hello guys. I take some intraoral photographs in the dental clinic using 70d and 100 2.8L. The combo works well, but sometimes I don't like the colors of the mouth tissues, even if shoot RAW. Once in a while I read very nice reviews about some other macro lenses (e.g., Voigtlander SL 125 2.5, Schneider Makro-Symmar 90mm 4.5, Leica R 100 2.8 APO) and I'm wondering if these lenses will give me some better image quality and color rendition?

All pictures I take are manual only, Canon Macro flash, ISO 100, shutter speed 1/100-1/150 sec and the widest aperture is 22 (I typically use aperture 32). Considering these parameters, would any of the above mentioned lenses give me any advantage over Canon 100L?

Another question is does anyone know if I cut a gray card to a small size to fit into the mouth, would I be able to more or less correctly adjust colors in LR?

Thank you!

I've never done any underwater photography, but I would imagine that the loss of light as one moves into deeper waters would limit things a lot. Lo and behold, I ran across this nifty housing made for the Canon 600EX-RT while browsing Adorama's website. This has got to be real cool for those that work underwater, and since Canon's flash works via radio it must open up all kinds of possibilities!

Has anyone here done any underwater flash photography using speedlites? I'd love to see some photos!

Here's a link to the housing:

I haven't had a lot of time to really intensively use my 7D II yet, but I've already noticed a couple of quirks that are contrary to what I understand to be true both in forums like this and also in the manual. I have 2 5D IIIs and have previously used 3 1st generation 7ds. All of those bodies have allowed me to select AF focus points using the rear dial (vertical movement), the joystick (omn-idirectional), or the top dial (horiontal). The manual for the 7DII states that such should be true of this body as well (page 81 of the manual). That's what confounds me. When I spin the top dial to select points (something I do in my sleep with the other bodies), rather than move the AF points, the camera simply cycles through the AF modes, which I find extremely frustrating. Is this how the camera works for everyone else? Am I misreading the manual when it says that the top dial should change the horizontal focus points? Is this a flaw with my body?

Secondly, I have the Sigma 300-800 f5.6. I also bought the just released TC-1401 Sigma 1.4 teleconverter to use with the lens on the 7DII. This combination should effectively provide me with f8 and should allow autofocusing using group G and center AF point. (page 86 of manual) When mounted, the camera registers f8, but regardless of which AF mode or zone selected, nothing initiates autofocus with this combination. Again, is there a trick I'm missing? Am I not understanding the manual? Does anyone know about any incompatibilities between this lens+tele combo and the camera I'm not aware of?

I appreciate any thoughts, suggestions, corrections to my understanding, or otherwise helpful comments. Thanks.

I have a D10 point and shoot, and about once in 100 shots the fish, my ability, and the slow autofocus allow me to get a shot I really like. I suspect that the newer D30 is better, but not enough. I have some big trips coming up, and would like to have faster autofocus, a better sensor, and external flash.

On the other hand, I do a lot of free diving and only a little scuba. A huge housing for my 5D III and six feet of flash arms would be too much to move around with. I'm guessing that a fairly small external flash and arm for snorkel shots to 20 feet (depth, not subject distance) would be enough, but with the option to change to bigger flashes for scuba.

I saw some good posts from the past, but the model information is probably out of date. What is out there these days?

Oh - my budget is somewhat flexible. To get most of what I want for under $1000 would be tempting, but I could go quite a bit higher for TTL-capable flash and a not-too-tiny sensor. The only thing non-negotiable is focus/shutter lag. I'm sick of waiting 5 seconds or more for the shot to take while my composition goes from good to bad to hopeless.

A few shots from last week. Happy to share details on kit, conditions and exposures.

Note to self: take a 7DMKII next time. Only have full frame and there was plenty of light but even my 600II + 2XIII was short at times.

Hi.

I have a question about how to use the 600ex rt for analoge photography. I have tried to read the manual, but I am a bit confused.

What I have done so far on my Mamiya RZ 67 pro ii is to trigger the flashes With the PW Plus X, and I lightmeter it With my Sekonic 758 Cine With the PW chip. This Works well, and is all manual..

However, I have heard that it is possible to get the flash to do some Limited Reading done for me... Is it possible to have the flash in the coldshoe on my Hasselblad 500cm (With the PC sync cord to my Hasselblad leaf shutter lenses), or other times, the PW in the coldshoe Connected to the lens, thus lightmetering/getting a read on the correct amount of light before firing off camera? A friend of mine who uses Nikon tells me he can put in his ISO, Aperture, and Focal range into the flash, so it reads the scene, and gives the right amount of light..

A) is this possible With my canon flashes (600ex rt)?
B) how fast can I sync the canon flashes, given that my hasselblad has max shutterspeed of 1/500 second?

Thank you,

Gerhard.

I'm wondering if the Wondapaner filter system will work with the new Canon ef 11-24mm f4 L lens?
It uses the largest diameter filters currently available. They are like dinner plates, nearly as big as the front element on a 400mm f2.8 LIS (I know because I currently have both). I use my Wondapanner with my TSE 17L and it's possible to achieve max shift in all directions and be vignette free. It's great to be able to use a polariser or a 3 or a 5 stop ND. The ND isn't very neutral but it's useful when an exposure blend is required to get the right shutter speeds. I find on the TSE-17L that I can only use one filter at a time with full shift. But if I stack 2 filters, I loose a few mm of shift. The flare with these filters is pretty bad, far worse than the naked lens element. Which leads me to think that these 145mm filters are not very well coated compared to the native lens...and one has to ask why they are SO expensive as a result.

PhotographyFirst · Mar 4, 2015

I've been looking at many sample photos from the 11-24 at 11mm. So far I have spotted some copies with poor centering at 11mm. At $3000, you should be demanding perfect performance.

Here is one example. If I am incorrect about my observation, please let me know. Check the lower corners. On a 5Ds, this is going to be way worse.

If you need help with checking with centering, I have a 16-35L guide in the education section of my website which shows you how. It applies to all lenses.

Sigma is hinting at upcoming "unique" lens, risky and odd like their 18-35 f/1.8.

Sigma Rumors is thinking it may be a trifocal lens. http://sigma-rumors.com/2015/03/sigma-upcoming-very-unique-lens-thoughts/

I guess the idea is it could be optically simpler and would not have to be good at every FL, just the 3 of them?

<strong>(Reuters) – Canon Inc (<span id="symbol_7751.T_0">7751.T</span>)</strong> Chief Executive Fujio Mitarai said his company had the funds and willingness for more acquisitions this year after a planned 23.6 billion Swedish crown ($2.8 billion) takeover of network video surveillance leader Axis AB (<span id="symbol_AXIS.ST_1">AXIS.ST</span>).</p>
<p>Mitarai has been leading efforts to find higher-growth businesses to complement Canon’s imaging expertise, and help the Japanese company expand beyond a camera market under attack from smartphones sporting competitive image-capturing capabilities.</p>
<p>Canon’s offer for Axis represented a premium of nearly 50 percent to the stock price before the announcement, a price some analysts said was high enough to ward off rival bids.</p>
<p>“If you buy a cheap company, you need to spend on drastic restructuring,” Mitarai told Reuters in an interview on Tuesday. “I only buy good companies, even if they’re expensive.”</p>
<p>Canon, which earned over 80 percent of revenue overseas in 2014, said it would pay for its biggest purchase ever in cash. It held 845 billion yen ($7.05 billion) in cash and cash equivalents at the end of December.</p>

Its not new and nobody says its perfect, but I needed a fast 50mm and least expected to end up ordering this lens. I felt I was taking a bit of a chance, considering various adverse comments on the web, but wow...I am enormously impressed. I wrote an initial review here (http://thephotofundamentalist.com/?p=1605) and will follow it up, but I have seen enough to realise that this is one of the few modern character lenses. It is far from perfect. It is not an ideal all-rounder IMHO, due to weight, size and cost (as well as some optical compromises), but as a 'people lens' it is absolutely phenomenal.

Looks like a lot of the harshest criticism is down to user issues like focus calibration, focus accuracy and movement (its f1.2) as well as some design compromises, but oh boy am I glad this lens is NOT one of the many perfect lenses we see nowadays. That would kill it as a portraits lens IMHO. So glad I bought one before there is a risk of a new Mk II version with 'improvements' LOL.

I am itching to use this lens for serious work. Alongside the 85 f1.2 L II... for portraits...well, what more could you want?

I will admit that I have been very frustrated by Canon's inability to produce bodies with more dynamic range, but lenses like this remind me of why I have not left the Canon stable.

We’re told that the next L lens from Canon will be a prime and it will be coming in late summer/early fall of this year. While the source wasn’t sure what lens was coming for sure, they did let us know that prototypes for a replacement of the 35L were out there. This has been a long rumoured lens for replacement, with multiple patents for the optical formula throughout the years.</p>
<p>For the moment, lens production capacity is what will dictate when new lenses are announced. The brand new EF 100-400mm f/4.5-5.6L IS II has been out of stock around the globe at major retailers for a long while now, so I’m sure that has priority for Canon. As well as the brand new and highly touted EF 11-24mm f/4L.</p>
<p>The only other primes I’ve had multiple discussions about are replacements for the EF 200 f/2L IS and EF 800 f/5.6L IS. Just like the 35L however, those mentions have been around for years. Interestingly, there hasn’t been talk of new TS-E lenses in a long time.</p>
<p>Outside of that, we’re still waiting on a new non L 50mm lens as well as a non L/non DO 70-300 replacement.</p>

Anybody know if there are any plans for a firmware update to address the focusing issues for the 7D Mark II? I recently upgraded and my images are just ok. Far from tack sharp. It seems Canon has sacrificed some image quality for speed :-\ I am trying to figure out if I want to sell and get the 5D Mark III or hold out for a firmware update. Kinda Bummed out as I waited so long for this camera.

Thanks!

The flood of reviews for the brand new Canon EF 11-24mm f/4L are starting to come in. I think the theme of all the reviews is going to be the same. “Yes, it costs a lot, but it’s awesome”. I’m still waiting to receive mine, and watching other people shoot with it is not a good substitute while I wait.</p>
<p>PetaPixel is next with their review of the lens and it includes a lot of sample images.</p>
<blockquote><p>“The Canon EF 11-24mm f/4L USM is heavy and bulky. It is also thrice as costly as the Sigma, which offers slightly narrower focal length and less brightness. However, if image quality (in terms of distortion and sharpness) and flare control is important to you, then there is really no contest between the two lenses. The Canon EF 11-24mm f/4L USM is an outstanding performer in the rarefied group of ultra-wide SLR zoom lenses, by itself or compared to other super wide zooms.”</p></blockquote>

Just curious.
I wanted best 85mm set up at aperture F2.

I have 70D and 50L.

Would image quality be better if I got 6D and 85mm 1.8 instead?

image quality refer to wow effect - sharpness, color, contrast, etc.

I've got a Yongnuo YN-565EX attached to a Plus X on a stand using a pc sync cord
and I've got a Speedlight 600EX shoe mounted on my Canon t4i attached through a pc sync cord to a plus X

when i press the "test button" on the Plus X attached to the 600ex, both flash's fire

However when i take a photo from my t4i, only the flash 600ex attached on my camera fires and not the Yongnuo YN-565EX. Both the Plus X are on the same channel
this is really frustrating and i've got no idea whats happening, why isn't the two Plus X talking to each other when i take a picture !
Please help

I noticed that there is no AV +/- exposure compensation button on the back of the new T6s. (There is on the T6i). Will there be an easy way to use exposure compensation on the T6s that does not involve going into a menu?

My rapidly emerging favorite video camera is the Panasonic GH4. Mine runs firmware V 1.1.
Firmware V 2.1 is available.

My GH4 is fully set up with complex, evolved custom settings in the C1-C3 options. I'd hate to lose these.
Do firmware updates over-ride or delete custom settings?

I am going to Sedona and the Grand Canyon (south rim) next week and am trying to decide on which of my lenses to bring, and better yet, which lenses I should rent. I am very interested in landscape shots, dessert foliage shots, as well as trying out some night shots. We will also be taking a helicopter tour over the canyon.

I have a 50D and the following lenses:
> EF 28-135mm f/3.5-5.6 USM IS
> EF 50mm f/1.4 USM
> EF 70-300mm f/4-5.6 USM IS

I love my 70-300 lens, which is great for wildlife shots; but not so great for wide landscapes. While the 28-135 kit lens is ok, I think I want something wider. I was thinking about renting the EF 16-35 or the EF 24-70, as well as the EF-S 10-22. Any thoughts or suggestions?

Also, would any of these lenses also be good for night landscapes or should I be renting another lens for that?

I really appreciate any suggestions you might have on what lenses would be best to bring on this trip.

Thanks!

Hi all,

Whew...has been quite awhile since I last posted anything...I gotta get back with it.

Anyway, I was toying with the idea of buying one of the SLR Magic's Anamorphot Anamorphic lens adapters, and was wondering if anyone had any experience with these yet.

Here's some links:
http://provideocoalition.com/awi/story/review-slr-magic-anamorphot-133x-50-anamorphic-adapter
and
http://www.eoshd.com/2014/02/new-slr-magic-anamorphot-film-seb-farges-look-diopters-close-focus/
and
https://www.youtube.com/watch?v=cFDKIatbjdM&spfreload=10
And
https://www.youtube.com/watch?v=bBPQTfkSzFg&spfreload=10

Now..one of the things I'm trying to figure..is will this work with ANY of my current EF lenses. It says the taking lens can be no more than 50mm in diameter...lens diameter, not filter diameter. I'm having problems finding out what lens diameter my lenses are.

That being said, I saw that the Anamorphot has stepper rings of 49mm, 52mm, and 58mm...and the adapter itself is 62mm.

So, looking at my lenses, it seems my L stuff is too large? I think the 70-200 f/2.8 is 77mm on the filter size, as is the 17-40L and the 24-105L. So, I guess my best glass won't work with this thing, eh?

I do have the 85mm 1.8 at it appears to be filter ring of 58mm, and the 40mm pancake is about 52mm filter size, so guessing since those match the stepper ring sizes these would work.

But can someone confirm this...I need to make sure the lens diameter is 50mm or less.

Anyway, like I said, it appears my good glass might not be compatible. That being said...what canon glass WOULD work with this thing? What with quality would work? Is there a quality zoom that would work with it?

Anyway, I would really love to play with anamorphic for my video work and my initial research on what's out there for this is prohibitively expensive and this lens setup, with the diopters looked like a reasonable way to get into this format.

So, anyone have experience with this? Recommendations for lenses, etc?

Thanks in advance!!

MikeT · Mar 2, 2015

This past weekend I got my new 100-400mm L IS II and immediately shot off a round of photos to check it. I notice that there is CA at 100mm (both green and purple), visible only when viewing at 1:1 or 2:1 (very visible). The CA occurs at any aperture at 100mm, but not at 200mm+. My 70-200mm L IS II does not show CA at any length. Did I get a lens that is, perhaps, poorly aligned, or is this simply an unrealistic expectation of pixel-peeping perfection? I realize that this can be easily fixed in PP, but if the lens is out of alignment, I would prefer to get one that is better.

Thanks for any help...

Mike
